How can you modify the init function to reset a scatter plot's data points before animation frames update?
ADo nothing; scatter resets automatically.
BUse <code>scatter.clear()</code> and return None.
CUse <code>scatter.set_offsets([])</code> and return the scatter artist.
DSet scatter data to None and return an empty list.
Step-by-Step Solution
Solution:

  1. Step 1: Understand scatter plot data reset

    Scatter plots use set_offsets to update points; setting empty offsets clears points.

  2. Step 2: Return the scatter artist

    Returning the artist allows FuncAnimation to redraw it properly.

  3. Final Answer:

    Use scatter.set_offsets([]) and return the scatter artist. -> Option C

  4. Quick Check:

    Reset scatter with set_offsets([]) [OK]
Quick Trick: Reset scatter points with set_offsets([]) [OK]
Common Mistakes:
  • Using scatter.clear() which does not exist
  • Returning None instead of artist
  • Assuming automatic reset
